PWM Signal Generator Module 0-150kHz square wave output

PWM output, adjustable frequency and duty cycle.Frequency is divided into four ranges, which switches automatically:

• XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz, ie. 100 indicates PWM output 100Hz pulse;
• X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz, ie. 1.01 indicates PWM output 1.01K pulse;
• XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz, ie. 54.1 indicates that the PWM output has a pulse of 54.1 kHz;
• X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz, ie. 1.2.4 indicates that the PWM output is 124 kHz pulse; 

Parameter settings: the module has four independent keys, used to set the frequency and duty cycle, supports short press (increase or decrease a unit) and long press (fast increase or decrease).
